I have one, would not sell it, great 50-75 yard carbine. Really like it. I would check the on line auction forums like gunbroker.com. I have not seen any at the local gun shows.
I have the PC40. It is a HAMMER with CorBon ammo. It is accurate too - I can hit a paper plate at 100 yards pretty easily. For some reason the .40's seem to be easier to find on the used market than the 9mm version, not sure why. I really like mine.
